Talking to Crowhood the Olden in Fens of Nathsar at ( -2631, -396, -2104 ) /waypoint -2631, -396, -2104 (northeast of Bellywhumper Burrows, Dragon's Rest is the closest sokokar post to her location) reveals that she lost her medicine bag.

You can find said medicine bag on the body of Guagua north of her swimming near ( -2721, -475, -2265 ) /waypoint -2721, -475, -2265.

Take the medicine bag to Crowhood and receive the actual Quest The Dream Scorcher.

Kunzar Jungle: near the Iksar Village close to Jinisk, at the ledge with the grave (climb up to ( 180, 87, -417 ) /waypoint 180, 87, -417)

Inspect the nearby grave (you have to speak Ykeshan) and prepare for a fight with four nightbloods (level 84) that spawn almost immediately. Move them away from the grave, because after them, another nightblood named Incubaa (Level 84, Heroic, ^^^) spawns. He fears, knockbacks and hits pretty hard, so you should bring friends.

Mizzog tells you to create something to protect your mind (four items and a medicine bag to carry them) and provides you with a list of ingredients, a recipe and a sewing kit. If you lose one of them, the box next to Mizzog can be harvested to receive those things again.

You need (in any order though you will need Huntmaster clasp to make medicine bag):

Head back to the grave at ( 180, 87, -417 ) /waypoint 180, 87, -417, and talk to Shulatu Darkskar, a ghost, who will ask you to subdue eight animal spirits.

The animal spirits are located all around Kunark and require you to use the spell Spirit Sight, (Defiler Spirit Sight), which Shulatu will give you. All of them should have a knockback and stun. They are single-player mobs but level 84, so it won't hurt to at least bring one other person with you. They roam in circles about the following locations:

Return to the grave, start the ritual (click on the mound). Bring a group, because after Shulatu's speech, a series of heroics will spawn (2 waves: of 3 and 4, 83^^). Kill them and Shulatu Darkskar's ghost (84^^^). Accept the rings.
